Title: Low pressure valve for container building - has spring-loaded diaphragm biased by pressure in work chamber to operate valve.
Inventor: SCHNEIDER FRIEDHELM
IPC: F16K17/04
Filed: 1992-12-07
Abstract: The pressure in the work chamber (3) acts on a spring- loaded (1) diaphragm (2) which through the flange tube (4) and valve seat bell (5) opens the valve gap (7) sealed by an O-ring (6) when the pressure determined by the force of the spring (1) is exceeded. In the event of excess pressure in the work chamber the diaphragm can be supported against the spring and with under pressure in the chamber the membrane can act against the force of the spring. Pressure compensation takes place through the opening in the event of excess or underpressure. USE/ADVANTAGE - Low-pressure valve to prevent overpressure or underpressure in sealed building.

Title: Detection and identification of sensor errors e.g. for aircraft controller
Inventor: KROGMANN UWE
IPC: G06N3/063
Filed: 1992-12-24
Abstract: The sensor produces a measurement vector m = H.x + e , where m is a vector of the measurement parameter, x is a vector of a state parameter being measured, H is the measurement matrix and e is the error vector. The order of m is greater than that of x. Validation vectors are determined as the column vectors of a projection matrix. A characteristic vector is determined as the linear combination of the validation vectors with corresp. elements of the measurement vector.The functional relationship between the characteristic vector and the corresp. classification vector is defined using a neural network whose connection wt. between its input and output layer is adapted during a training phase. The neural network contains only forward combinations between more than two layers of processor elements.

Title: Method and apparatus for purifying exhaust gas
Inventor: BOEHLER HARALD
IPC: F26B25/00
Filed: 1993-04-14
Abstract: An exhaust gas 4 which comes, for example, from a wood-drying installation is purified in a washer 1 by means of washing liquid 9 circulated in the circuit 8. Washing liquid laden with washed-out pollutants is fed via a branch line 10 to an evaporation container 12 which is provided with a heating device 15. The pollutants accumulate in high concentration in the liquid thickened in the evaporation container 12 and can be eliminated with the thickened liquid via a discharge line 13. The arising steam is fed to a condenser 19 via a compressor 23 in order to be returned into the circuit 8 via a return line 18. A partial flow 30 of the steam condensate can likewise be drawn off in particular if the washing-liquid volume increases through condensate from the exhaust gas 4. The heat of condensation from the condenser 19 can be used for the evaporation of the washing liquid in the evaporator 12. <IMAGE>

Patent DE-4325297-A1 (DE)
Title: Single-part interchangeable spectacle frame
Inventor: HUEESMANNS HERBERT
IPC: G02C1/06
Filed: 1993-07-28
Abstract: If, for cost-saving reasons, one selects spectacle frames with interchangeable lenses, but only lower half-frames with side pieces (ear pieces) and bridge piece, the prior art shows frames comprising a plurality of individual parts, a stiffening section, which runs over the lenses, for example an upper frame with a fastening to the lower frame being necessary. A lower half-frame without an upper frame could be bent when the spectacles are put on or taken off. This problem is solved in that the lenses (4) have at the outer upper four ends a vertical T-shaped or angular reinforcement (7) or (8) which are seated in a matching groove (3), (5) or (6) in the lower frame (1) and thus stabilise the lower frame (1) between the side piece and the bridge piece. The lenses (4) are slid in and out from above with little friction relative to the lower frame (1). If protection is desired for the upper lens edge of this lower frame (1), a lens rider (slide) (2), which matches the lower frame (1) and has a groove (9), is fitted in different sizes and in a detachable manner on the lenses (4), without fastening relative to the lower frame (1).

Title: Thermostatically controlled radiator valve, especially for tubular radiators
Inventor: REISERER WERNER
IPC: F24H9/12
Filed: 1993-09-07
Abstract: Known valve fittings are arranged outside the tubular radiator and have corresponding connections for the feed and return, which means that the feed must pass via pipes outside the radiator. The intention of the invention is to provide a radiator valve, especially for tubular radiators, which allows the feed to be admitted within the radiator using the first member. For this purpose, a cylindrical valve main body (2), in which the valve insert (14) is arranged axially with a closing body (15) that can be adjusted axially relative to the valve seat, is arranged directly in the hub (1) of the first radiator member, which acts as a rising pipe and admits the feed (VL). The valve main body (2) is connected to the circular openings in the hub (1). Arranged in the valve main body (2) is at least one radial hole (3), which is connected to a central axial main hole (4) which, in turn, opens in the direction of the valve insert (14) into the interior (5) of a sleeve-shaped extension (6) of the valve main body (2). At least one return hole (7) leads off coaxially with the main hole (4) from the interior (5) of the sleeve-shaped extension (6) into the hub (1a) of the following member. <IMAGE>
